First, they didn't "close the source". The new license is not closed source. You can argue why you think the license is bad, but it is not closed source.
Second, I don't know about you, but continuing to function in the same way is my primary need for systems I am managing. When my provisioning system installs a package by name, i expect it to work in the same way as before. Switching binary names breaks that promise.
My setup has scripts that do things like check that a process named "redis" is running... this will break if the process is now called "valkey"
I feel like all the commenters live in some kind of crazy alternate world where purity of license matters more than stability of systems.

But where do you put the blame?
The distro for making that change, or the redis company for breaking your software stack?

And there's a entry from 2011 in urbandictionary.com, so maybe that's around when it was coined.
